JOHN K. BOSWELL, OF RICHMOND, INDIANA.

DRY-HOUSE.

Specification forming part of Letters Patent No. 57,669, dated September 4, 1866.

To all whom it may concern:

Be it known that I, JOHN K. BOSWELL, of Richmond, Indiana, have invented certain new and useful Improvements in Dry-Houses; and I hereby declare the following to be a full and exact description of the construction and operation of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon,in which- Figure l is a perspective view of the dryhouse. Fig. 3 is a vertical section at the red line to x,- and Fig. 2 is a top view, showing the air-chamber and its valves.

In Fig. 1, A A represent the framing of a box or structure of rectangular form, B being the top of the same, and capable of being removed. D is the furnace, and E is the door of the same, constructed so as to slide up and down, allowing more or less draft in the furnace. O is the door. I l are bearings attached to the inside of the structure to support poles or cords. a. a are openings in the structure, filled with glass. F is an open or latticed platform, placed upon legs or posts rising above and protecting the rectangular heater G, which is placed near the bottom of the dry-house.

The furnace D discharges the heat through the pipe (1 into the heater G, where it is deflected right and left, as shown by the arrows, passing through the openings h h in the valves H H, and escaping into the chimney I) through the pipe G.

H H are cylindrical tubes fitting closely into the heaterpipe, and provided with a handle or lever, 70, and an opening, it, by means of which the current of heat may be partially or entirely shut off upon either side of the heater,

The chamber 0 e c e is formed by incasing the furnace D with any suitable material, and serves to equalize and radiate the heat generated immediately in the furnace, and is supplied with air through the openings 1 i in the bottom of the chamber.

In Fig. 2, K K are openings connecting the interior of the dry-house with the air-chamber forming the top of the structure, said openings being opened or closed by the operation of the sliding valves J J, actuated by the rods 0 c, the handles of which project through the inclosure of the structure.

The heated air, passing through the openings K K, passes through the pipe 1) into the chimney I), thus producing a strong draft through the interior of the dry-house, which may be modified as desired by means of the sliding valves J J.

The open platform F can be taken out of the dry-house and replaced at convenience.

Having thus fully described my said invention, whatI claim as new, and desire to secure by Letters Patent, is

1. The rectangular heater G, when the same is provided with the cylindrical valves H H, as and for the purposes set forth.

2. The combination of the rectangular heater (l, the valves H H, the openings K K, and the connecting-pipe b, all arranged and operating substantially as and for the purposes set forth and described.

3. The arrangement of the movable latticeplatform F and rectangular heater G and valves H H, substantially as set forth.

JOHN K. BOSWELL.
